Well, what is on the other end of the GPIO ? If this is a button, you
may want to set the interrupt type to edge, otherwise the interrupt will
remain asserted as long as you press the button, and you will get an
interrupt storm. If it is another GPIO, then you should reset that GPIO
state in the irq handler.
Also, it may actually be simpler to write an RTDM driver than to use the
deprecated, error-prone rtintr API.
